4/29/2023 0 Comments Glock 40 mos![]() While I was definitely aware I wasn’t firing a 10mm, recoil was not prohibitive, with accurate rapid shots possible. G40 MOS accuracy was excellent, producing small clusters out to 15 yards.ĮVTC TacStrike steel targets were rocked with a more substantial smack than a typical handgun round. The Glock polymer frame and overall size of the G40 MOS absorbed and mitigated felt recoil. Range testing took place at Echo Valley Training Center (EVTC).įederal Vital-Shok 180-grain Trophy Bonded 10mm Auto and Buffalo Bore were the stoutest loads, but in no way harsh or unmanageable. Hornady 155-grain XTP chronoed 1,242 fps from the G29, 1,309 fps with the G20, and 1,406 fps out of the G40 MOS. Velocity gain between a 3.7- inch Glock 29, used for comparison, and the six-inch G40 MOS was in the 100 to 120 fps range.īuffalo Bore 180-grain JHP clocked in at 1,320 fps from the G29 and 1,445 fps from the longer-barreled G40 MOS. The 6.02-inch barrel gets the most out of the 10mm Auto in terms of velocity. Three 15-round magazines arrived with the G40 MOS. Width is 1.27 inches and weight empty is 28 ounces. A length of 9.5 inches provides an extended 8.2-inch sight radius. ![]() The G40 MOS is a true “long slide,” reminding one of 17L 9mm dimensions. Glock MOS allows for multiple red dots to be mounted. Critical Duty, as the name implies, was designed with law enforcement in mind, though security-conscious citizens would be amiss not to at least consider it. The nickel-plated cases are another attention to detail nod that limits drag into or out of a weapon’s chamber, limiting chances for failure to feed or extract. The ogives of the Critical Duty bullets do not taper as much as other hollow-point bullets, which improves feeding characteristics in autoloaders. The FlexLock bullet nose prevents the hollow-point from deforming or clogging when passing through barriers. Variety of 10mm Auto ammunition was accessed for use in evaluating Glock G40. Hornady Critical Duty passed all five of the FBI’s barrier criteria tests, giving 12 inches plus of penetration no matter if through glass, sheet metal, heavy clothing, drywall, or plywood, while still expanding for maximum wound channel as well as not passing through the ballistic gel test medium. The Hornady Critical Duty FlexLock bullet balances barrier penetration with proper expansion in the target for maximum effectiveness. Hornady has also taken full advantage of recent advances in propellant technology, using low muzzle flash powder in Critical Duty ammunition. The jackets are locked to the core via the same InterLock process the company uses on its centerfire rifle bullets. The Critical Duty’s FlexLock bullets have a heavy jacket and a harder high-antimony core designed to defeat barriers. ![]() These Hornady loads were designed with personal defense in mind, with XTP and Critical Defense bullets loaded at 1,150 to 1,250 fps. Premium 10mm Auto loads from Hornady were used, consisting of 155-grain XTP and 175-grain FlexLock Critical Duty. Buffalo Bore hard-cast loads are an excellent option for anyone contemplating using the 10mm Auto for hunting. ![]() Hard-cast bullets are not “lead” bullets as most associate with the term. True hard-cast bullets (as opposed to lead swaged bullets) that are properly lubed will not lead foul polygonal barrels any more than any other type of rifled barrel. This goes against typical warnings related to lead bullets and is because of the differences between soft lead “cowboy” bullets and hard-cast bullets. Buffalo Bore hard-cast bullets are not verboten with the Glock polygonal rifling. Glock G40 MOS is a “long slide” variant similar to the 17L featuring a six-inch barrel.īuffalo Bore is another prime source of true 10mm Auto ammunition, offering several bullet types ranging from hard cast to JHC and FMJ-FN. This kind of power offers great flexibility for the user in terms of use in personal defense or hunting medium-size game. This load delivers 650 foot-pounds of energy, which puts it roughly between the. The load features a 180-grain bullet that leaves the muzzle at 1,275 feet-per-second (fps) compared to the usual 1,030 fps of many manufacturer offerings. The bullet used with the Federal load is based on the proven Trophy Bonded Bear Claw rifle round featuring a jacket with formed inner profile that controls expansion to ensure deep penetration. Trophy Bonded 10mm Auto shows the cartridge’s potential. ![]()
